Gromov–Witten theory of $[\mathbb{C}^2 / \mathbb{Z}_{n+1}] \times \mathbb{P}^1$

Abstract

We compute the relative orbifold Gromov–Witten invariants of [2n+1] × 1 with respect to vertical fibers. Via a vanishing property of the Hurwitz–Hodge bundle, 2-point rubber invariants are calculated explicitly using Pixton’s formula for the double ramification cycle, and the orbifold quantum Riemann–Roch. As a result parallel to its crepant resolution counterpart for 𝒜n, the GW/DT/Hilb/Sym correspondence is established for [2n+1]. The computation also implies the crepant resolution conjecture for the relative orbifold Gromov–Witten theory of [2n+1] × 1.
